Looking for freewheel clutch
Looking for freewheel clutch
(OP)
I'm looking for any kind of freewheel clutch system that would fit inside thoses dimensions :
inside diameter = 35 mm
outside diameter = 52 mm
total length = 25 mm (including seals on both sides)
The system must be able to support a small radial load (about 200 lbf) and to transmit a torque of maximum 10 lb*ft only. Any standard one-way bearings I can found on the web (SKF, NTN, INA, Torrington, etc.) are very overdesign for theses dimensions, and they always exceed my maximum length. I tried to found some ratchet or freewheel system, but I don't know any producer.
The application is for a recreational vehicule transmission (a couple of thousands piece per year), so the part has to be as cheaper as possible. Someone has an idea?

They make sprag-type and their own type one-way clutches, ratchet assemblies, etc.

Related to the rear axle part of a 10-speed bicycle, I precisely have one of them on my desk! I suppose it could work, but I can't find one for my dimensions : It has to be inserted over a 1" 3/8 (35 mm) and it must not exceed 2" outside diameter (52 mm). I don't know where can I find that?
The Briggs starter will not work... My clutch system will turn continualy over 2000 RPM, a centrifugal freewheel would be always disengaged.
Thanks for your comments, don't hesitate if you have any other idea!
